Respuesta :
So you divide by 2 because there is 2 buildings. You get 760. Now, just take 200 away from one building, and 200 away from the other, and you get 560 for Building A, and 960 from Building B.
Given A=B-200
A+B=1520
(B-200)+B=1520
2B=1720
B=860ft
A=860-200
A=660ft
A+B=1520
(B-200)+B=1520
2B=1720
B=860ft
A=860-200
A=660ft
